Double-jointedness occurs when there are two joints between bones that are normally governed by one joint

1 answer:

6 0

THis is absolutely false. It is often an action of hypermobility of the joints that helps to produce the limber effect that we see which is often termed as someone being double jointed while in fact they are singularly jointed not double jointed.

Which statement describes a reason that the output of molecules of cellular respiration are different from the input molecules?

dimulka [17.4K]

Answer:

The bonds between the atoms in the input molecules are broken and new bonds are formed to produce the output molecules.

Explanation:

Cellular respiration is a metabolic (catabolic) process carried out by the cells of all living organisms because it is the way usable energy in form of ATP is obtained. All organisms feed in order to acquire energy, the energy is stored in the chemical bonds of the digested food (glucose).

The process of cellular respiration then breaks down the food molecule in order to release the stored energy and convert it to ATP, which is the energy currency usable by the cell. The general equation of cellular respiration is:

C6H12O6 + 6O2 -----> 6CO2 + 6H2O

Since the energy is initially stored in the bonds of the input molecule (glucose), the bonds needs to be broken in order to assess the energy. Hence, cellular respiration breaks the bonds in the input molecules and rearranges the atoms by a new bond to form the output molecules (CO2 and H2O).

Joseph Unahue made his fortune in "Food Distribution"

<u>Answer:</u> Option C

<u>Explanation:</u>

The Nuyorican president of Goya Food named Joseph Andrew Unanue. The firm was largest United States owned Hispanic food company, operated by the Unanue family.

He enrolled at the Catholic University of America in Washington, D.C., in 1946, after Unanue returned home from battlefield of World War-II, where he graduated with a degree in Mechanical Engineering. Along with his brothers Tony and Frank Unanue, he joined the family business.

Firstly major supermarkets like A&P and Safeways were not motivated in selling anything considering the Hispanic demographics.Finally, the grocery industry began to take note with the influx of Hispanic immigrants settling in the United States. Goya Foods started supplying "Safeway's Harlem Grocery" and developed ahead.

High doses of caffeine interfere with the dna replication checkpoint mechanism in mammalian cells. why then do you suppose the s

Kipish [7]

Molarity = $\frac{Solute(in Moles)}{Solution (in Liters)}$

Moles of Caffeine = Mass of Caffeine/Molar Mass
Mass = 100 mg = 0.1 g
Molar Mass = 196 g/mole

Moles of Caffeine in one cup = 0.1/196 moles
= 5.102 * 10^-4 moles

If one cup of coffee is ingested (A typical adult contains about 40 liters of water),

Molarity of caffeine = [(5.1 * 10^-4)/ 40] M
= 0.012755 mM

The toxic molarity of caffeine in the body 10mM

How many cups will be toxic?
= Toxic Molarity/ Molarity of 1 cup
= 10/ 0.012755
= 784

In other words, you would have to drink 784 cups of coffee to reach the dose required to interfere with the DNA replication checkpoint mechanism.
